Description

Technical Field

[0001] This utility model relates to the field of water outlet device technology, and more specifically, to a temperature-sensing water outlet device and a water outlet. Background Technology

[0002] Currently, water dispensing devices are widely used in showerheads, faucets, and various other water terminals to output water from the water supply system in the desired manner. In situations involving hot water use, changes in water temperature directly affect user safety and comfort; therefore, water dispensing devices capable of controlling or switching water flow based on temperature variations are gaining increasing attention.

[0003] Existing technologies primarily employ electronic control, using temperature sensors in conjunction with control circuits and actuators to control water flow. However, this type of structure is relatively complex and costly. Furthermore, its reliability is poor under prolonged use in harsh environments such as humidity, hindering its widespread application in compact bathroom products. In particular, conventional control methods are often used for water temperature mixing or simple on / off control, making it difficult to quickly and effectively switch between different water outlet positions or states based on water temperature changes. Moreover, after water pressure changes or prolonged use, issues such as unstable operation, uneven switching, and inaccurate water outlet positions can easily arise. Additionally, due to their large size and insufficient integration, they are difficult to adapt to existing miniaturized and lightweight water outlet applications. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a temperature-sensing water outlet device and a water outlet to solve the above problems.

[0005] The present invention adopts the following solution: This application provides a temperature-sensing water dispensing device, including an outer body with an inlet and an outlet, and a fixed base, a support base, and an inner core disposed in the outer body. The fixed base contains a piston chamber that allows the inner core to move axially. The outer body contains a switch assembly for controlling the flow of water into the piston chamber. The inlet has a trigger element linked to the support base. The support base is movably disposed within the fixed base and is used to elastically abut against the inner core when no water enters the piston chamber. In its initial position, the trigger element positions the inner core in a first water dispensing position. After sensing temperature, the trigger element switches to a working position and drives the inner core to move to a second water dispensing position via the support base, thereby switching between different water dispensing conditions along the outlet.

[0006] As a further improvement, the trigger is configured to be installed on the fixed base to detect the temperature head, and the support base abuts against the end of the temperature head. After hot water is input at the water inlet, the temperature head is triggered to expand by sensing the temperature, so as to drive the support base and the inner core to move relative to each other.

[0007] As a further improvement, the switch assembly includes a reset plug abutting against the water inlet channel of the fixed seat, a push button hinged to the side wall of the outer body, and a reset member for holding the push button in a normally closed state; after the push button is pressed, the plug is driven upward to avoid the water inlet channel, thereby allowing water to enter the piston chamber of the fixed seat laterally.

[0008] As a further improvement, when water enters the piston chamber, the inner core is driven away from the support seat and brought closer to the outlet end by water pressure to switch to the third outlet position; and the inner core is provided with a through-hole outlet nozzle for outputting the water flow entering the piston chamber to the outlet end.

[0009] As a further improvement, the fixing seat includes an upper seat body and a lower seat body that are tightly connected by threads, with the water inlet channel formed in the upper seat body and the piston cavity formed in the lower seat body.

[0010] As a further improvement, the support is disposed in the upper body and extends partially into the lower body, and a spring is provided abutting between the support and the lower body.

[0011] As a further improvement, another spring is provided between the inner core and the inner wall of the lower seat to abut against the support seat with corresponding elastic force.

[0012] As a further improvement, the lower seat body is connected to the water outlet end, and a water outlet channel connecting to the water outlet end is opened at its bottom; multiple water inlet holes and multiple water outlet holes are opened on the outer periphery of the lower seat body, and water enters the seat body through the gap between the outer body and the fixed seat through the water inlet holes, and water exits the seat body through the piston cavity and is input to the water outlet end.

[0013] As a further improvement, a water inlet connector is welded to the water inlet end, and a flow controller is built into the water inlet connector.

[0014] This application also provides a water dispenser, including a water outlet terminal and the aforementioned temperature-sensing water outlet device; the water inlet of the temperature-sensing water outlet device is connected to an external water supply source via a flexible hose, and the water outlet is connected to the water outlet terminal via another flexible hose.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects: The temperature-sensing water dispensing device of this application directly responds to temperature changes through a trigger element to drive the support base, thereby pushing the inner core element to freely switch the water dispensing position. It does not require an additional power supply or electronic control mechanism, making its structure simpler and its working principle more reliable. It is extremely suitable for long-term use in humid and other harsh environments. The fixed base is equipped with a piston chamber and a switch component for controlling the water inlet and outlet of the piston chamber. After switching on, water can enter the piston chamber and directly dispensing water to the outlet end. By using the different water dispensing positions corresponding to the first and second water dispensing positions of the inner core element, various water dispensing conditions can be realized, such as automatic switching from high flow rate to low flow rate, and from spraying to atomization. This expands the product's functions and improves the user experience. After sensing the temperature, the trigger element is in the working position, switching the inner core element to the second water dispensing position. This can quickly and directly change the water dispensing mode or reduce the flow rate, thus reducing the risk of scalding. It is especially suitable for use by children, the elderly, and other sensitive groups. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0019] Example Combination Figures 1 to 10 This embodiment provides a temperature-sensing water outlet device, including an outer body 1 with an inlet and an outlet, and a fixing base (made of...) disposed in the outer body. Figure 1 The system comprises a lower seat 8 and an upper seat 9, a support seat 6, and an inner core 3. A piston chamber, allowing the inner core to move axially, is correspondingly provided within the fixed seat. A switch assembly for controlling the water inlet / outlet of the piston chamber is correspondingly provided on the outer body 1. A trigger 10, linked to the support seat, is provided at the water inlet end. The support seat 6 is movably disposed within the fixed seat, and is used to elastically abut against the inner core 3 when the piston chamber is not filled with water. In its initial position, the trigger 10 places the inner core 3 in a first water outlet position. After sensing temperature, the trigger 10 switches to a working position and, through the support seat 6, drives the inner core 3 to move to a second water outlet position, thereby switching between different water outlet conditions along the water outlet end.

[0020] The temperature-sensing water outlet device described above directly responds to temperature changes through the trigger element 10 to drive the support base 6, thereby pushing the inner core element 3 to freely switch the water outlet position. It does not require an additional power supply or electronic control mechanism, and its structure is simpler and its working principle is more reliable, making it extremely suitable for long-term use in humid and other harsh environments.

[0021] The fixed base is equipped with a piston chamber and a switch assembly for controlling the water inlet and outlet of the piston chamber. After the switch is turned on, water can be directly discharged to the outlet end by entering the piston chamber. By using the inner core 3 at different outlet positions corresponding to the first outlet position and the second outlet position, various water discharge conditions can be realized, such as automatic switching between high flow rate and low flow rate, spraying and atomization, etc., expanding product functions and improving user experience.

[0022] After sensing the temperature, the trigger element 10 is in the working position, thereby switching the inner core element 3 to the second water outlet position. This can quickly and directly change the water outlet pattern or reduce the flow rate, thus reducing the risk of scalding. It is especially suitable for use by children, the elderly and other sensitive groups.

[0023] It should be noted that the fixed seat provides clear axial limitation and guidance for the support seat 6, ensuring that the support seat 6 moves only in a predetermined direction within the fixed seat. This guarantees that the inner core 3 moves stably axially when driven, avoiding deviation, shaking, or jamming. Simultaneously, the support seat 6 is arranged in a restricted manner within the fixed seat and elastically abuts against the inner core 3 when water is not entering the piston chamber. Under the constraint of the fixed seat, the inner core 3 can be stably held in the first water outlet position, reducing the problem of initial position instability caused by water pressure fluctuations or external disturbances.

[0024] like Figures 1 to 5 As shown, in this embodiment, the trigger 10 is configured to correspondingly pass through and be installed on the fixed base as a temperature sensing head, and the support base 6 abuts against the end of the temperature sensing head. After hot water is input at the water inlet, the temperature sensing head is triggered to expand by sensing the temperature, thereby driving the support base 6 and the inner core 3 to move relative to each other. Thus, the temperature sensing head can directly sense the inlet water temperature and generate displacement through thermal expansion. Specifically, the temperature sensing head is installed at the water inlet and passes through the fixed base, allowing it to directly sense the temperature of the water flowing into the cavity, reducing temperature measurement lag and improving the accuracy of switching timing. In particular, the end of the temperature sensing head directly abuts against the support base, and the displacement is transmitted to the inner core through the shortest mechanical transmission path, resulting in high mechanical efficiency and faster action transmission.

[0025] Preferably, the temperature sensing head is a temperature sensor. The temperature sensor can quickly and accurately detect changes in the water temperature at the inlet, which helps to promptly trigger the relative movement of the support base and the inner core when the water temperature reaches a preset threshold, thereby improving the response speed and accuracy of the water outlet state switching.

[0026] like Figure 1 and Figure 5As shown, in this embodiment, the switch assembly includes a plug 14 that abuts against the water inlet channel of the fixed base, a push button 15 hinged to the side wall of the outer body 1, and a reset member 17 for keeping the push button in a normally closed state. After pressing the push button 15, the plug 14 is driven upward to avoid the water inlet channel, thereby allowing water to enter the piston chamber of the fixed base laterally. Thus, the mechanical operation of the push button 15 can directly control the opening of the plug 14, so that the piston chamber can only be laterally filled with water when the user presses it, which facilitates manual filling of the piston chamber to increase the water flow at the outlet, thereby directly switching the inner core 3 to a larger flow rate through water pressure. Preferably, a washer 13 is fitted around the outer periphery of the plug 14, which tightly blocks the water inlet channel. Furthermore, the push member is hinged to the outer body 1 by a pin 16, which facilitates pressing operation and automatic reset.

[0027] Specifically, when water enters the piston chamber, the water pressure drives the inner core 3 away from the support 6 and closer to the outlet end, thus switching to the third outlet position. By directly using the water pressure entering the piston chamber as the power source to drive the displacement of the inner core 3, no additional power input is required, resulting in a simpler structure and higher operational reliability. In particular, in addition to the first and second outlet positions, the inner core 3 can also be driven by water pressure to the third outlet position after water enters the piston chamber, enabling the water outlet device to achieve at least three different outlet states, enhancing the diversity of water outlet functions and the added value of the product.

[0028] Understandably, the inner core 3 is configured as a mandrel, with multiple sets of Y-rings 4 or damping rings fitted around its outer circumference. These rings are used to flexibly fit within the piston cavity, serving a dual function of sealing and damping connection. Furthermore, after moving to the second water outlet position, multiple rings are used to partially block the water inlet 23 or obstruct the water outlet 24 from flowing directly to the water outlet, thereby extending the water outlet path.

[0029] Furthermore, the inner core 3 is provided with a through-hole spout 22 for outputting the water flowing into the piston chamber to the outlet end. By forming a through-hole spout 22 on the inner core 3, the water flow in the piston chamber can be quickly transported to the outlet end along a straight path, reducing unnecessary deflections and local resistance, improving water output efficiency and reducing energy loss. Moreover, when the inner core 3 is driven by water pressure and switches to the third outlet position, the water flow is output through the spout 22 inside the inner core 3, preventing water flow around or leakage, and ensuring continuous and stable water output in the third outlet state.

[0030] like Figure 1As shown, in this embodiment, the fixing seat includes an upper seat body 9 and a lower seat body 8 connected by threads. The upper seat body 9 has a corresponding water inlet channel, and the lower seat body 8 has a corresponding piston chamber. Clearly, placing the water inlet channel in the upper seat body 9 and the piston chamber in the lower seat body 8 makes the water inlet control and drive chambers structurally independent, with clear functional division, which is beneficial for optimizing their respective structures and working performance. Furthermore, the threaded connection between the upper seat body 9 and the lower seat body 8 reliably improves the coaxiality of the inner core 3's axial movement, reducing the risk of misalignment and jamming. The threaded connection between the two seats facilitates the provision of a sealing surface at their joint, effectively preventing leakage between the water inlet channel and the piston chamber, and improving overall sealing performance.

[0031] Furthermore, the support base 6 is disposed within the upper body 9 and partially extends into the lower body 8. A spring member 5 is abutted between the support base 6 and the lower body 8. Correspondingly, another spring member 2 is abutted between the inner core member 3 and the inner wall of the lower body 8, used to spring the inner core member 3 against the support base 6. It can be understood that one spring member 5 provides independent reset and buffering force for the support base 6, while the other spring member 2 provides independent preload and contact force for the inner core member 3, allowing the support base 6 and the inner core member 3 to be controlled separately at each stage, improving the adjustability and stability of the overall movement. In the initial state or when the water pressure is low, the inner core member 3 and the support base 6 always maintain a tight and effective contact, avoiding problems such as gaps, idle strokes, or delayed response.

[0032] In this embodiment, the lower seat 8 is connected to the water outlet end, and a water outlet channel communicating with the water outlet end is opened at its bottom. Multiple water inlet holes 23 and multiple water outlet holes 24 are opened on the outer periphery of the lower seat 8. Water enters the seat body through the gap between the outer body 1 and the fixed seat through the water inlet holes 23, and water exits the seat body through the piston cavity through the water outlet holes 24 and is input to the water outlet end. Specifically, an O-ring 7 is fitted on the outer periphery of the lower seat 8 to block the water inlet holes 23 and water outlet holes 24 in the gap.

[0033] like Figure 3 and Figure 6 In the first water outlet state, the trigger 10 is in the initial position, the support 6 and the inner core 3 are in elastic contact, and no water enters the piston chamber. At this time, the inner core 3 is in the first water outlet position, no water enters the water inlet channel, and no water is discharged from the outlet 22. The water flow at the inlet end directly enters the fixed seat through the gap between the outer body 1 and the fixed seat along the water inlet hole 23 and is then directly guided to the outlet end, thereby outputting a large flow of water.

[0034] like Figure 4 and Figure 7In the second water outlet state, the temperature-sensing trigger 10 switches to the working position, pushing the support base 6 and causing the inner core 3 to move to the second water outlet position. At this time, no water enters the inlet channel, and hot water enters the fixed base through the gap between the outer body 1 and the fixed base along the inlet hole 23. Due to the piston-like movement of the inner core 3, part of the inlet hole 23 is blocked, and the blocked water flow is guided to enter the outlet end directly from the body of the base, changing the water outlet path. This causes the water outlet 24 to exit the body of the base along the piston cavity, greatly reducing the water flow rate and thus outputting trickle water.

[0035] like Figure 5 , Figure 8 , Figure 9 and Figure 10 In the third water outlet state, after water enters the piston chamber laterally, the water pressure drives the inner core component away from the support seat 6 and moves it closer to the outlet end. At this time, the water flow along the inlet channel and the water flow entering the inlet hole 23 along the gap converge in the seat body to the outlet nozzle 22 and be guided to the outlet end, thereby outputting jet water along the outlet nozzle 22. At the same time, the water flow input into the seat body along the inlet hole 23 can be diverted to be directly guided to the outlet end (outputting the large flow of water mentioned above), and output to the outside of the seat body along the outlet hole 24 and then input to the output end (outputting the trickle water mentioned above).

[0036] In a preferred embodiment, an inlet connector 11 is welded to the inlet end, and a flow controller 12 is built into the inlet connector 11. Obviously, the flow controller 12 can limit or regulate the incoming water flow rate, keeping the water pressure and flow rate of the entire water outlet device within a preset reasonable range during water outlet operation. Furthermore, the inlet connector 11 has an external thread, and correspondingly, the outlet end has another external thread integrally formed at the end of the outer body 1, allowing both ends to be screwed into external hoses respectively.

[0037] Combination Figure 11 This embodiment also provides a water dispenser, including a water outlet terminal 18 and the aforementioned temperature-sensing water outlet device. The inlet of the temperature-sensing water outlet device is connected to an external water supply source via a flexible hose 19, and its outlet is connected to the water outlet terminal via another flexible hose 20. The water outlet terminal can be, but is not limited to, a shower head, a water nozzle, a kitchen faucet, or other domestic or industrial water-using device. Specifically, the flexible hose 19 is connected to a water inlet base 21 and then to the water supply source, while the water outlet terminal 18 is preferably a shower head device, used to be mounted on the water inlet base 21.

[0038] On the one hand, the temperature-sensing water dispensing device can automatically or manually switch its inner core to different water dispensing states based on water temperature and pressure, thereby achieving multiple water flow modes and anti-scalding protection functions at the water dispensing terminal, improving safety during use. On the other hand, the flexible hose connection facilitates the flexible placement of the water dispenser and the water supply terminal, adapting to different spatial layouts and installation requirements.

[0039] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
